There was a post in one of the Facebook vintage groups from someone who has
Epson QX-10 Q10CMS and Q10GMS boards. The GMS is what I have in my own
QX-10, but does anyone know what the CMS board is?
Both boards have a NEC 7220 graphics controller, but the CMS appears to
have more on-board memory (384KB vs. 256KB). On the other hand, I'm not
seeing any on-board ROM in the photo of the CMS, unlike on my GMS.
